Good job on getting into running! I would highly suggest you find some "exercises for runners" videos on youtube and find some exercises that are comfortable for you to do. Focus on the exercises that are asymmetric(lunges etc). You can do most of them at home and it takes 30 minutes twice a week. You will feel the results in less than two weeks. Most of the people who run consistently do those kind of exercises because running is very demanding on your body and if stabilizer muscles are weak, the impact will go to your joints and tendons.
